This is the fourth time i have experienced an Act ending and every time +/- one or two weeks before the end of the act i notice my skill level dropping, the game seems a lot harder and i have trouble maintaining my rank and often i drop 2 ranks. Comp games and even Deathmatch games seem way more difficult than 'normally'.

I'm for sure not the best player but i'm generally happy with my rank, but this is not only a bit frustrating but it really takes the fun out of the game.

Is this something more people experience or am i imagining things at the ending of Act?
